Diet, Circulating Estrogen Levels and Estrogen Excretion

  • Barry R. Goldin
Part of the Reproductive Biology book series (RBIO)


There have been a number of reports of increased frequency of breakthrough bleeding and pregnancies in women taking oral contraceptives and antibiotics simultaneously (1–4). One affect of the possible mechanism for this is the ability of antibiotics to interfere with the enterohepatic circulation of estrogens (5). Diet may also influence estrogen cycling and therefore impact on the effectiveness of oral contraceptives. The relationship between diet and plasma estrogen levels and excretion patterns are the subject of this report.
